Specification of Letters Patent.

Patented June 9,1903- Application filed May 29, 1907. Serial No. 376,400.

To all whom it may concern:

Be it known that I, ALTON F. .TOWLE, a citizen of the United States, residing at Colorado Springs, in the county of El. Paso and State of Colorado, have invented certain new and useful. Improvements in Engines, of which the following is a specification. I

This invention relates to improvements in that type of engine, wherein the cylinder and. the iston containing it are both reciprocated in order to derive power from the pressure of motive fluid against the cylinder heads.

A primary object of the nascent invention is to provide novel means a simple nature, whereby the steam. or other motive lluid is admitted. to the nigovablc cylinder without the necessity of fieiible cou alings, swinging pipes and the like, and. the cylinder is inc-lose so that the full effect of the steam is secured and condensation avoided. i

A further and. important object is to improve the engine in certain details of construction so that the same is more practical and effective. a 4

The referred embodiment of the invention is i lustrated in the accompanying drawings, wherein Figure 1 isa top plan view of the same. Fig. 2 is a side elevation. Fig. 3 is a longitudinal. sectional view. Fig. ytis a cross sectional view. Fig. 5 is a horizontal sectional view.

' Similar reference numerais designate cortory 0. ends .0 which are t 'ireaded rings 10. Heads 11 are bolted, as shown at 12 to said rings.

The cylinder slides upon a lower bearing strip 13, and has its opposite sides 15 .--formed upon the diametricall inner sides of the casing or steamc est. The cylinder, as shown in Fig-t 4 is of less diamc ter than the bore of the casing or steam chest,

outstanding guides 14 on and consequentlythe steam or motive fluid can pass freely around 1t.

responding parts in all the figures of the.

that operate in guideways opposite controlled by a valve.

linder com rising a body 9, 1n the ,der; There willthus b A reciprocatory piston l (i is mounted} in the cylinder, and a piston rod17,,connecte-d thereto, projects through .a.suitable stuffing hox 18 in one head of the cylinder and through another stuliinghogclg the casing head, said rod being connected; o'a suitabl cross head 20. The cylinder has also (get nected thereto cylinder rol 2 1 thati s lide through stuffing boxes 22- in t c casiifigl ead,

An engine shaft 24 is provtdedsyith oppositely dis osed cranks 25, and pit ni n 26, connected to said cranks, h 'ave suitahle'connections with the cross heailsQO and 23.

The cylinder is providediat its, en t l s ;with ports 27 that communicate ,with the interior of the casing or steam chest inwhichjsefid cylinder is located.

From the foregoing, it is thought that the construction, operation and many' advantages of the herein described invention will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size, shape, pro; portion, and minor details of construction, may be resorted to without departing from the spirit or sacrificing any of the advantages of the'invention.

, Havin thus fully described my invention,- what I c aim as new, and desire to secure by a Letters Patent, is
